How It Works

                
This tool generates a random IPv4 address. You can customize the generation by selecting the options below to ensure the generated IP meets your specific needs. The tool operates completely client-side in your browser, so no data is sent to a server.


                
IPv4 Address Structure

                
An IPv4 address consists of four numbers, called octets, separated by periods. Each octet can range from 0 to 255. This generator creates each octet as a random number between 1 and 254.


                
Valid Public IPv4 vs. Private/Reserved

                    
Enable filters to avoid non-public blocks. Common special-use ranges include:

                    
    
                    
  • Private (RFC1918): 10.0.0.0/8 · 172.16.0.0/12 · 192.168.0.0/16
    • 
                    
  • Loopback: 127.0.0.0/8
    • 
                    
  • Link-local (APIPA): 169.254.0.0/16
    • 
                    
  • CGNAT: 100.64.0.0/10
    • 
                    
  • Documentation: 192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24
    • 
                    
  • Benchmarking: 198.18.0.0/15
    • 
                    
  • Multicast & reserved: 224.0.0.0/4 and 240.0.0.0/4
    • 
                    

                    
Note: Even with filters, generated IPs are random and may not be routed or assigned.




                
Excluding Private and Broadcast Ranges

                
    
                    
  • Private IP Ranges: These addresses are reserved for use within private networks (like your home or office network) and are not routable on the public internet. The tool excludes the following ranges:
                        
      
                            
    • Class A: 10.0.0.0 to 10.255.255.255
      • 
                            
    • Class B: 172.16.0.0 to 172.31.255.255
      • 
                            
    • Class C: 192.168.0.0 to 192.168.255.255
      • 
                        
    
                    
    • 
                    
  • Broadcast Addresses: An IP address ending in .255 is a broadcast address and is used to send data to all devices on a specific network. These are often not needed for general use.
